Knowledge of local child safe guarding procedures are necessary for all working in this field. Recommendations on basic and advanced skills required are specified. This paper was written to compliment a full review document. The complexities around case management, child protection issues and competing family motivations require dietitians trained at undergraduate and postgraduate level to deliver high quality weight management and behavioural change.

Herein, we reported a series of naphthalene derivatives substituted with chiral branched alkyl chains, which are present as liquids (Nap1-3) or solid (Nap4) at room temperature, depending on the substitution positions. Circular dichroism (CD) and circularly polarized luminescence (CPL) were only observed for enantiomeric Nap2 (2,3-substituted) liquid. It is suggested that the chiral aggregation in the π-liquid leads to the CD signal and the chiral excimer resulting in the CPL performance. When achiral anthracene or pyrene was dissolved in Nap2, the π-liquid could serve as chirality and energy transfer media in which both CD and CPL emerged from the achiral anthracene. A CPL dissymmetry factor (|glum |) of anthracene reached to 5.2×10-2 when dissolved in chiral Nap2 liquid, which is nearly two orders of magnitude higher
